T 0 all whom it may concern:

Be it known that 1, JOHN HENDERSON, a citizen of the United States, residing at Cadillac, in the county of \Vexford and Stateof Michigan, have invented a new and useful Stove, of which the following is a specification.

The present invention appertains to stoves, and aims to provide a. novel and improved'stove adapted especially for use in chicken brooders, chicken coops, and the like, although the stove may be employed for divers purposes for which it is suitable.

One of the objects of the invention is the provision of a stove which can be suspended within the brooder, coop, or the like, whereby the chickens can rove under the stove, the stove being rotatable whereby it can be properly attended to without the necessity of the attendant or operator walking completely around the stove, and the means which suspends the stove serving to carry off the products of combustion.

Another object of the invention is the provision of a stove of unique construction, the same having an annular fire boX or combustion chamber, and having a unique assemblage of the component parts, wherebythe heating capacity and efficiency of thestove are enhanced.

The invention also includes a hood above the stove and assembled with the suspension means, whereby the hood can be raised and lowered relative to the stove as desired \Vith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and inthe details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can bemade within the scope of what is claimed without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawings, wherein Figure -1 is a view of the improved structure, one half being shown :in elevation, and the other half beingshown in verticalsection. Fig. 2 is an enlarged horizontal section taken on the line 22 of Fig. 1, one half of the stove being illustrated in plan and the other half being illustrated in section, portions being broken away. tional detail taken on theline 3-3. of Fig. 2.

The stove embodies a cylindrical casing Fig. 3 1s a sec-,

cal suspension pipe or flue 5, and the casing 1 is rotatably carried by the lower end of the pendant flue 5. 'To this end, a ring or annular casting- 6 is riveted or otherwise secured 'upon the top 2 of thecasing around the opening 4, and has an annular upstandng flange 7 providing a recess accommodatmg a collar 8 which is threaded or otherwise secured upon the lower end portion of the flue 5. An annular plate 9 is secured in any suitable manner upon the flange 7, and an annular series of anti-frictional balls 10 are disposed between the collar or flange 8 and the plate 9, said collar and plate being provided with suitable annular ball races for accommodating the balls. The plate 9 which is attached through the medium of the ring 6 to the stove casing, may therefore run upon the balls 10 to allow the casing to be rotated freely. The flue 5 not only acts as a suspension means for the stove, but also serves to carry off the products of combustionfrom within the stove casing.

Disposed within the verticalcasing 1 is a vertical cylindrical drum, 11 of smaller diameter than the casing 1 to provide an annular space between said casing and drum, and the drum 11 has a conveXed or domeshaped top or upper end 12. -The upper end of the drum 11 is provided with a flange 13 riveted or otherwise secured to the top or head 12, and the top 12 ofthe drum 11 is disposed adjacent but spaced from the convexed or dome-shaped top 2 of the casing.

A plurality of short pipes or flues 15 are engaged through the tops 2 and 12 of the casing and. drum respectively, around the ring 6, and nuts 16 are threaded upon the ends of the lines 15 and bear against the upper and lower surfaces of the tops 2 and 12, whereby the fines 15 not only provide outlets for the upper ends of the drum 11,.

but also serve the office of stays for connecting the tops of the casing and drum, whereby the drum is held in place wlthin the casing; The drum, as well as the casing, is constructed of sheet metal.

Disposed between the casing land the drum .11, that is, between the side walls thereof, is an annular series of'radial stays 17 having downturned cars 18 at their ends bearing against the side walls of the casing and drum, and radial bolts 19 are engaged through the cars 18 and the side walls of the casing 1 and-drum 11 to secure the stays 17 in place, and to also secure the casing 1 and drum 11 to the ends of said stays. The stays 17 assisted by the fines .15 serveto hold the drum' 11 concentric with the casing 1. The stays 17 are disposed between the upper and lower ends ofthe casing and drum. The stays 17 also serve to support an annular grate 20 which is seated thereon, this grate 20 having suitable slots or openings 21 for the upward passage ofair therethrough, and for the downward passage of ashes into the annular ash pit below the grate. The annular fire box or combustion chamber is located above the grate between the casing 1 and drum 11, and the flue 5 serves as an outlet for the products of combustion. posed of upper and lower annular sheet metal plates 22 having an ,annular sheet of asbestos or fire proof material 23 therebetween, registering slots -or openings being provided in the plates 22 and sheet 23.

The top 2 of the casing is provided with a number of fuel openings 24 abovethe annular firebox at various points around the center of the stove, and the openings '24 are normally closed by covers 25 seating upon the top 2 over said openings, the cover 25 being preferably hinged, as at 26, to the top 2.

The casing 1 and drum 11 have a common bottom, which embodies a pair of semi-circular sections 27 having their side edges hinged together and to the lower ends of the casingand drum, as at 28, and the free portions of the sections 27 are normally held in place against the lower end of the casing 1 by means of pivoted catches 29 carried by diametrically opposite sides of the casing 1 adjacent the lower end thereof. The catches 29 are engageable under the free portions of the sections 27. When one catch 29-.is released, the correspondingsection 27 of the bottom can be swung downwardly for taking out the ashes, or the like, and when both catches 29 are released, the bottoms of the casing and drum are completely opened. Each section 27 of the bottom is provided with an arcuate or semi-circular upstanding flange 30 adjacent its margin, andwith a second arcuate or semi-circular flange 31 between the flange 30 and the center of the bottom, and the flanges 30 and 31 of the two bottom sections coeperate to overlap the lower ends of the casing 1 and drum 11,

The grate 20 is preferably comrespectively, upon the outer sides thereof. This provides a tight joint between the bottom and casing and drum.

' The air is supplied within the annular ash pit below the grate 20 by means of an annular series of inwardly projecting nozzles 32 having their outer ends attached to the casingl between the grate and bottom, the side walls of the casing 1 having openings 33 registering with the nozzles 32 to admit air. 7 The outer ends of the nozzles 32 have outturned annular flanges 34, and rings 35 are slipped upon the nozzles 32 and bear against the flanges 34, said rings 35 being fastened by means of bolts or other securing elements 36 to the casing 1 whereby the nozzles are clamped in place. The passage of airthrough the openings 33 and nozzles 32 is controlled by an annular damper 37 constructed of sheet metal or other suitable material, the same as the casing and drum and their bottom. An'umber of outstanding orradial bolts 38 are secured rigidly to the casing 1 between the openings 33 and their outer or free ends are engaged through elongated horizontal slots 39 with which the annular damper 37 is provided, whereby the damper-is guided for rotary or oscillatory movement around the stove casing. The damper 37 is provided with inwardly offset portions 41 cooperable with those portions of the casing 1 having the openings 33, whereby when the damper 37 is rotated or oscillated, the portions 41 can be moved over and away from the openings 33 to control the flow of air therethrough as will' be evident. The bolts.. 38 can be loosened or tightened to allow the damper to move easier or harder, whichever is preferred, and the damper 37 is provided at suitable points with handles or knobs 40 whereby the damper can be actuated from various sides of the stove casing.

The means for hanging or suspending the fine or pipe 5 embodies an upper ring or collar 42surrounding the flue 5 at some distance. above the stove, and wedge blocks 43 are driven between the ring 42 and fine, 5 for holding the said line in place relative to said ring, wherebythe flue isnot liable to slip downwardly under the weight of thestove.

The ring or collar 42 has a lower rounded ,or concaved portion 44 seating in an opening 45 provided in the horizontal supporting plate 46, whereby the flue 5 can swing relative to the supporting plate 46, so that the flue 5 will come to a true vertical position, the stove acting as a plumb bob. This plate 46 may be attachedto the ceiling, frame or other support, by means of hangers 47 having turn buckles 48 for adjusting them, any suitable number of hangers 47 being employed. The hangers 47 have hooks for engaging in apertures of the plate 46, and the upper ends of the hangers 47 hav ing eyes or other suitable means for attaching them to the support.

A dome-shaped hood d9 of greater diameter than the stove casing, is slidable vertically upon the flue'5, the exterior surface of the hood, 49 being preferably covered with asbestos or equivalent material 50. Secured upon the crest or central portion of the hood I9 is an annular plate or ring 51 which is slidable upon the flue 5, said flue serving as a guide for guiding the hood $9 for vertical movement above the stove.

In order to enable the hood +19 to be raised and lowered, the plate or ring 51 has upstanding eyes or elements 52 engaged by the loops 53 of cables or flexible elements 54, said loops 53 being made secure by clamps The cables 54: pass over pulley wheels or sheaves 56 carried by the supporting plate 46. The pulley wheels 56 are pivoted between pairs of hangers 57 rigidly secured to and depending from the plate 46. The cables 5d may be extendedto any suitable point whereby when the cables are operated the hood can be raised and lowered, and if desired a suitable counter balance may be attached to the cables to allow the hood 49.

to be moved to any suitable position and to remain in said position.

In use, the stove may be suspended within the brooder, coop or the like, by attaching ucts of combustion pass upwardly between the casing l and drum 11, and thence between the tops of said drum and casing, and finally up through the flue 5. Air is admitted through the openings 33 and nozzles 32 into the annular ash pit, and passes upwardly through the grate to support the combustion of the fuel, the amount of air admitted being controlled by the adjustment of the annular damper 37. It is to be noted that the air surrounding the casing is not only heated, but the air within the drum 11 is also heated, the heated air passingupwardly through the flues or outlets 15 from the drum 11. The hood 49 serves to catch the heated air, and prevents the same from rising upward, whereby the heated air is directed to all sides from the edge or rim of the hood.

The flre withinthe stove may be supported below one or more of the openings 2 1, according to the amount of heat desired, and the stove may be suspended sufliciently above the floor to allow the chickens to rove under the stove. The suspension of the stove above the floor also permits one or more partitions to be disposed below the stove for segregating the chickens, yet allowing the various groups of chickens to stand below the stove. The stove will practically have a uniform heat throughout all sides thereof, and the hood 49 may be adjusted vertically to the desired height above the stove, according to the circumstances. The hood can be let down over the stove, whereby the heated air is confined within the hood, and is directed downwardly from the stove. The stove can be revolved about a vertical axis, which enables the attendant to properly take care of the stove without walking around the same, and the annular damper permits the inflow of air to be controlled effectively, it being noted that the damper can be operated from any side of the stove. The stove has air inlets completely around the same, whereby the air is properly supplied to the the box.

The stove provides an admirable means for heating a brooder, chicken coop, or the like, although the stove may be put to various uses.
